P35 DS4 RAM settings

[Jonnygrunge]

Guys,
just upgraded my RAM on my mobo, I bought some OCZ blade series PC 9200 RAM, which I'm running stable at 5-5-5-15 @ 1.85V 1200MHz DDR, with a 3:2 FSB/RAM ratio. I have noticed a performance enhance option in the BIOS, offering standard, turbo or extreme settings I have in the past left it at standard but curiosity is getting the better of me! I am guessing it will automatically adjust RAM timings based on the overclock (FSB) am I right? I always like to set the standard timings manually, and leave the advanced RAM timings to auto. Is it worth changing the performance enhance setting?, If so will it offer any real world improvement?

Well thanks folks!, I went out and investigated the subject myself, drew a few conclusions and decided to give it a go!

For your info:
For the performace enhance BIOS setting, standard setting gave a performance level of 8 for my RAM at 5-5-5-15 (1200MHz 1.85V) From Everest.
Benchies are as follows (from everest):

Latancy: 60.2ns
Copy: 7701MB/s
Write: 7274MB/s
Read: 8460MB/s

With performance enhance set to turbo RAM performance level increased to 5 for my RAM, which is running at 5-5-5-18 (1200MHz 1.85V) Here are the benchies:

Latancy: 52.5ns
Copy: 8072MB/s
Write: 7276MB/s
Read: 9420MB/s

Tried the same tests with RAM at 5-5-5-15 but there was not a lot of difference, if any!, and the Tech at OCZ said "tRAS shouldn't really make any difference in performance, but may help a bit with stability so give 18 a shot" Very happy with my Blade series RAM hope this info helps!
